iOS
Beginning in September 2011, Linux Journal began offering custom iPhone and iPad apps. The apps are free to all and include one sample issue of the magazine as well as a constantly updated feed of news and stories. All paid Linux Journal subscribers also receive access to read their monthly issue from within either or both iOS apps as a part of their regular subscription.
iOS Apps Edition FAQ
Q. Where do I download the iPhone and/or iPad apps?
A. http://www.linuxjournal.com/ios
Q. I am not a subscriber. Can I still use the app?
A. Yes, but a limited version. Non-subscribers have access to our September 2011 issue free of charge so they can test-drive the magazine on their iOS device. There is also a continually updated feed of news and stories that is pushed out to the app for all to read.
Q. I am a subscriber and I have downloaded the iPhone and/or iPad app(s). Now what?
A. Login with the e-mail address we have on file for your subscription and you will receive access to your subscription's issues. If you have any trouble logging in, please e-mail us at gm@linuxjournal.com and we'll get you fixed up right away.
Q. Are back issues of Linux Journal available on either of the iOS apps?
A. Both apps have magazines dating back to the September 2011 issue. Subscribers, remember you can always access our PDF back issue library here (you'll need to login).
Q. Can I buy single issues of Linux Journal from within the iPhone and/or iPad app(s)?
A. Yes.
Q. If I subscribe to Linux Journal from iTunes or the App Store will I receive access to all other formats of the magazine?
A. No. Apple does not share subscriber data with us (this is a major complaint we in the publishing world have with Apple). While it is our practice to offer subscribers access to all formats we have available, because Apple doesn't tell us who you are, we can not set up that access for you. We encourage you to subscribe directly through Linux Journal so we can set up your full featured access, including to your iOS devices.
Q. Can I see a sample of the magazine in the IPhone and/or iPad app(s) before buying?
A. Yes. We invite you to sample our September 2011 issue free of charge. It will automatically load load for you once you download the app.
Q. I have an iOS app-related question not answered here. Can you help me?
A. Yes! Please e-mail us your question and we'll do our best to get you an answer. If it's a commonly asked question, we'll also post it here.
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
